Find LCM of 517,345,465,984,388 with Prime Factorization
| 2 | 517, 345, 465, 984, 388 |
| 2 | 517, 345, 465, 492, 194 |
| 3 | 517, 345, 465, 246, 97 |
| 5 | 517, 115, 155, 82, 97 |
| 517, 23, 31, 82, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 517 x 23 x 31 x 82 x 97 = 175920686040
Therefore, the lowest common multiple of 517,345,465,984,388 is 175920686040.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
517 x 345 x 465 x 984 x 388 = 31665723487200
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
517 : 1, 11, 47, 517
345 : 1, 3, 5, 15, 23, 69, 115, 345
465 : 1, 3, 5, 15, 31, 93, 155, 465
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,345,465,984,388, is 1.
Now, the common factors can be found like this.
517:11x 47
345:3x 5x 23
465:3x 5x 31
984:2x 2x 2x 3x 41
388:2x 2x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 5 = 180
Therefore, the value for common factors is 180.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 31665723487200/(1x180)
LCM = 31665723487200/180
LCM = 175920686040
Thus, we can understand that the LCM of 517,345,465,984,388 is 175920686040.
